- Abstract
The edge effect due to the special structure of two degree‐of‐freedom direct induction motor (2DoFDDIM) results in three‐phase asymmetric current, high torque ripple, more loss and low efficiency. In this paper, to weaken edge effect of 2DoFDDIM rotary part, poles optimization is carried out considering the constraint of rotary arc‐armature size. In order to obtain optimum parameters and high efficiency of rotary part, The Taguchi method of multi‐objective optimization design is carried out. The 3D finite element models of final design and initial design of rotary part and initial design prototype are established, respectively. Through the comparison between the final design simulation, initial design simulation and test results, the results indicate that the performances of 2DoFDDIM rotary part have a great improvement after optimizations and verify the feasibility of Taguchi method used for 2DoFDDIM multi‐objective optimization design. © 2021 Institute of Electrical Engineers of Japan.
